st02-03-04-06 how to interpret?

Hello,

in the tcode st02 st03n st04 and st06, there are many voices.

But which of them are most important for a quick bottleneck analyze?

Hi,

When the bottleneck is so big that you can't login to SAP system my first approach is doing the following command on UNIX level:

Dpmon pf=<instance profile>

In this way I can find the state of sevral parts of the system without login.

For Bottleneck Analysis..in short i check this way.

SM50 - WP status ( Find what is creating the block) A quick analysis would give its a SPACE [DB issue or at OS level issue]

If its OS go to -> ST06 (FileSys)(Memory) used at times

If its DB go to -> ST04 (State on disk - DB02)and Lock Wait situtations.

ST03N is utilised for User - Tcoide analysis and other stuff which is discussed at length in many threads.

Ifits an SAP (Application level) issue..then jump to ST22 and SM21 (My best frds)

Hope the inputs are helpful in some sense to make up your mind. Also awaiting inputs from others on their views

Hi

In my opinion the first check to be made is response time in ST03N. It is the first thing that would indicate a bottleneck. Average response times of the overall system can be seen in SMLG as well.

Hope that helps.
